Can I put "any" voltage in the slots for 3Dvoltage? Of course I mean within reason, but does it look for a specific set/group of voltages?

Yes, you can enter 1000 volts to these slots if you want. It depends on the card, what it makes of it. There are cards that seem to not have a changeable voltage transformer at all, but must cards transformers will limit at about 1.4 volts. RBE correctly programmes the BIOS to set the voltage entered, but due to hardware limitation, this might not be enough. You need to convince yourself using a multimeter to be sure about your voltages. If you reached the hardware limit, a hard mod (many tuturials can be found in the internet) is inevitable.

Does anyone know if this would work with the HD3870X2 BIOS and how one would go about Flashing the HD3870X2 with out bricking it (Preferable)? I read somewhere you need to flash it twice or something like that, which scares me cause HOW THE FUDGE WOULD I DO THAT??

Thanks.

Yes, you can alter a 3870 X² BIOS. Due to this card actually has 2 boards with 2 BIOSes, you have to flash the exact same BIOS file to both of the boards. I don't know if this can be done using WinFlash, but I'm certain ATIFlash can do the job!

Why don't you download this Computerbase program and see for yourself? It's a completely different program. It has it advantages, but there are several disadvantages just as a poor fan support for example or non-changable BIOS information.

Every one of us knows voltmod through modding the bios doesn't work with Powercolor HD 3850 cards. But i have HD 3850 from Sapphire, i tried to edit the bios with computer base ati radeon bios editor, no go. Is it possible to mod voltage in RBE?

The computer base program does pretty much the same as RBE: Programming the BIOS to set certain voltages.
If hardware doesn't put it into practice, it won't work! Use a hard mod, then.

Recently I upgraded my Asus Terminator P4 533A (initally purcheased barebone system in 2003) with a GeCube Ati Radeon HD 2400 Pro AGP 512Mb. Rest hardware in the system is a P4 2.4GHz, 1GB DDR RAM, onboard sound. The AGP slot is up to 4x, while the VGA card is up to 8x, but nobody is perfect!

Anyway, I needed some video card boost for my system in order to go on playing games. So I bought the above Ati HD 2400 Pro AGP.

My problem now is that the video card's fan is making some noticeable noise while the rest of the fan on CPU and case work only when temperatures rise (the fans also rise thier speeds). Ati's fan is working constantly, with no reduction in its speed. So I am thinking to use RBE and modify ATI's fan settings in the card's BIOS, so the fan will work in lower speeds.

Because it's the first time I am gonna flash my video card's BIOS I would like some help here, please!

Below, there are pictures of the BIOS taken from the ATI HD 2400 PRO AGP as it appears in RBE.

The last pic is from the alternation I did in the "Fan Settings" section in RBE, in order to lower somehow the fan speed of my video card.

1. Can someone tell me if this Ati HD 2400 Pro AGP 512MB BIOS has any control over its fan speed? RBE shows that normally this card's BIOS controls the fan as it is shown in picture 3 (look up table) before the alternation i made of course!

2. Is this change I am showing here at pic 4 at the look up table going to change the Fan speed of my video card?

RBE shows what's programmed to the fan controller on boot up. If the card ignores the controller, maybe by using a fixed fan voltage, the controller can control nothing of course. You can check using RivaTuner's hardware monitor whether your fan speed is really constant or the look up table values are being used.
Why don't you just hit the "set all settings to recommended values" button? If you really wanna use the look up table, you can do so but I think you should consider using transfer function because it is more sophisticated.

hi BAGZZlash! I'm new here and I registered to thank you for your very useful application! I've been having problems with the fan control of my GeCube HD 3850 (256MB). I set the fan this way:

The fan speeds up as temperature rises, I can here it! But the fan never go down even if the temperature already went down. It gets stuck at that speed. It will only reset if I reboot or put the computer to sleep. Does it have something to do with the PWM control? I set it this way:

Does flashing the BIOS using Winflash and ATIFlash have differences? I hope you can help me! Thanks again!

So is there someone in here that may know if Fan Regulation is possible in ATI RADEON HD 2400 PRO AGP 512MB through change in its BIOS?

Regarding the controller you state, is there any way that I might bypass it?

Using the "set all settings to recommended values" button, the graph changes with higher values. I will try to post a picture and show you what I mean. Transfer function is a nice solution, but I am first interested if this might work at all, regulating fan speed through BIOS.

The problem was solved! I used the BIOS from the TPU archive, edited the fan control and flashed it in DOS mode. The fan works now! I think it has something to do with Hysteresis, I set it to zero as well as the Tmin this time and it worked!
